Nikon Coolpix L320 (59.5mm) Friction-Fit Lens Cap
Just like the title implies... this Thing is a simple friction-fit lens cap for a Nikon Coolpix L320 camera. The modeled internal diameter of the cap is 59.5mm but when I printed it the actual measurement reduced down to about 59.2mm. Some tweaking may be needed to adjust for the right friction, depending on the 3D printer you have.
